Public Member Functions inherited from clang::dataflow::DataflowAnalysis< UncheckedStatusOrAccessModel, NoopLattice > | |
DataflowAnalysis (ASTContext &Context) | |
ASTContext & | getASTContext () final |
Returns the ASTContext that is used by the analysis. | |
TypeErasedLattice | typeErasedInitialElement () final |
Returns a type-erased lattice element that models the initial state of a basic block. | |
TypeErasedLattice | joinTypeErased (const TypeErasedLattice &E1, const TypeErasedLattice &E2) final |
Joins two type-erased lattice elements by computing their least upper bound. | |
LatticeJoinEffect | widenTypeErased (TypeErasedLattice &Current, const TypeErasedLattice &Previous) final |
Chooses a lattice element that approximates the current element at a program point, given the previous element at that point. | |
bool | isEqualTypeErased (const TypeErasedLattice &E1, const TypeErasedLattice &E2) final |
Returns true if and only if the two given type-erased lattice elements are equal. | |
void | transferTypeErased (const CFGElement &Element, TypeErasedLattice &E, Environment &Env) final |
Applies the analysis transfer function for a given control flow graph element and type-erased lattice element. | |
void | transferBranchTypeErased (bool Branch, const Stmt *Stmt, TypeErasedLattice &E, Environment &Env) final |
Applies the analysis transfer function for a given edge from a CFG block of a conditional statement. | |

TypeErasedDataflowAnalysis () | |
TypeErasedDataflowAnalysis (DataflowAnalysisOptions Options) | |
virtual | ~TypeErasedDataflowAnalysis () |
const std::optional< DataflowAnalysisContext::Options > & | builtinOptions () const |
If the built-in model is enabled, returns the options to be passed to them. | |
Public Member Functions inherited from clang::dataflow::Environment::ValueModel | |
virtual | ~ValueModel ()=default |
virtual ComparisonResult | compare (QualType Type, const Value &Val1, const Environment &Env1, const Value &Val2, const Environment &Env2) |
Returns: Same: Val1 is equivalent to Val2, according to the model. | |
virtual void | join (QualType Type, const Value &Val1, const Environment &Env1, const Value &Val2, const Environment &Env2, Value &JoinedVal, Environment &JoinedEnv) |
Modifies JoinedVal to approximate both Val1 and Val2. | |
virtual std::optional< WidenResult > | widen (QualType Type, Value &Prev, const Environment &PrevEnv, Value &Current, Environment &CurrentEnv) |
This function may widen the current value – replace it with an approximation that can reach a fixed point more quickly than iterated application of the transfer function alone. |
